Cat 5E patch cable for short runs

This Belkin A3L791-03 cable connects two RJ45 ports over a 3 ft distance. It is built for Cat 5E performance with bare stranded copper conductors at 24AWG across four pairs. The grey jacket is unshielded UTP, suited for standard home or office patching.

Typical thermal and power profile

As a passive copper cable it generates no heat, draws no power and produces no noise during operation. The 50 micron gold-plated contacts maintain low resistance without active cooling. Conductor resistance is rated at 89.2O/km/20°C max for reliable signal integrity.

Deciding specification: 3 ft length

The fixed 3 ft reach determines whether this cable fits between a wall jack and a desk device or between rack-mounted equipment. Longer runs will require a different length; shorter runs leave excess slack. Characteristic impedance is 100±15O @ 1 ~ 100MHz.

Questions about this item

How do I connect the RJ45 connectors and what step is often missed?

Align the tab on each RJ45 plug with the port slot and push until it clicks; the step often missed is confirming the latch is fully seated so the cable cannot pull loose.

What maintenance or replacement will this Cat 5E cable need over time?

No scheduled maintenance is required; replace the cable if the gold-plated contacts show corrosion, the latch breaks, or the jacket is kinked or cut.

What limit appears first during sustained high-frequency use?

The characteristic impedance tolerance of 100±15 Ω at 1–100 MHz is the first limit; beyond that range signal integrity degrades.
